To make Thousand Island Dressing: Stir together mayonnaise, relish, and ketchup in small bowl.

To make Sandwiches: Toast 8 slices bread. Set aside. Drain tempeh, and discard liquid, onion, garlic, and bay leaf. Place 3 slices tempeh on each slice of remaining bread. Top with cheese slices. Toast or broil 3 to 5 minutes, or until cheese has melted.

Top each sandwich with 1/4 cup sauerkraut. Spread toasted bread slices with Thousand Island Dressing. Place tops on sandwiches, and slice in half.
